Sorting out how bindings are added to name lookup. (#2869)

Browse Source 
This shifts logic so that bindings are added to name lookup only after the scope is complete, removing logic around adding/removing/re-adding names in certain scopes.

This does mean that things like a function's forward declaration will need to go through an extra hoop for name conflict checks, because under this approach a function definition does conflict checking when it adds names for the body's use. But, that seems easy to address, and better than the current hoops.
